Homework Help Forum request

To make things less of a headache for others, I'd like to try to use TeX, and make everything look nice and organized. After all, they're helping me for nothing, right?

Thing is, I use Preview Post to ensure I have everything right before submitting it... but every time I click Preview Post (Which is often, if I'm using TeX), it adds the "1) Type your problem 2) Type your relevant equations 3) Type your attempt at the solution)", over the span of 10ish lines.

So, Preview Post 6 times, and now I've got 60 lines to go delete :(

Can you make it such that 1)/2)/3) appear when making a new post, but NOT when submitting a preview?
